RPS in 4930 sprayers?

Hey,

After a HUGE scare here in the east hills of the willamette valley last week (rolling an Apache 1210 on to its top)

We are now officially looking for a cab that has RPS(rollover protection system), does the new JD 4930's have a tractor cab, like a 9220 cab? tractors by law have to have RPS. Apparently the law states only tractor cabs need RPS and not really anything else, dumb dumb law IMO.

by the grace of God everyone is OK from this frightening experience.

Thanks~

Re: RPS in 4930 sprayers?

Well the sprayer was fully loaded, today we had engineers out to look at the site, and turns out the slope was only 34% << not even close to our steepest ground around 48%.

It was the first solution tank this sprayer ever had in it, its very unfornate, but the driver.. my brother is re-couping slowly but surely he should get back to better health, but his back is broken in several places.

Hope he recovers completely.
Is it a new design? To heavy in the rear?
The JD 47X0 is very light at the nose end too, specially with the 90ft boom.
The 49x0 are better balanced.

Re: RPS in 4930 sprayers?

The weight distribution is MUCH better for hill climbing on the Deere, for one, Deere has a weight bracket and then the machine is able to have some front end counter balancing, secondly the back axle placement is placed to where the tank is completely in front of the rear axle,

Hard to see from my pics but the Apache has the tank sticking out over the back axle off the rear of the machine, thus when you go up a hill the center of gravity shifts much of the solution's weight farther back and raising up the front end, further complicating the machines performance on hill climbs as opposed to Deere.

I too wish your brother a speedy recovery. Never like to see that happen to guys.

In this sort of steep ground a front mounted sprayer has the advantage over the rear mounts for the very reasons of better weight balance all round. Also makes them climb better.
